The IO port type 8-bit microcontroller aip8p003h of micro AI core can replace Feiling fm8pe53

           Aip8p003h is an 8-bit CMOS microcontroller with low cost, high speed, high anti-interference and OTP ROM, which can replace fm8pe53 of Feiling.
Aip8p003h adopts RISC architecture with only 42 instructions. All instructions are single cycle, except that program branches require two cycles.
Aip8p003h internally integrates power on reset (POR), undervoltage reset (BOR), power on reset timer (PWRT), oscillator startup timer (OST), watchdog timer, OTP ROM, SRAM, three state IO port, IO pull-up / open drain / pull-down control, power-saving sleep mode, real-time programmable clock / counter, etc.

Aip8p003h LED screen driving scheme
The LED screen driving scheme developed based on aip8p003h can drive up to 42 led segment code screens through single line communication, and provide 3 programmable COMS output ports. The communication protocol can be customized (such as serial communication and proportional code communication).
Application scenario
The main advantage of this scheme is that it occupies very few ports. It only needs VDD, GND and one output port to drive the LED segment code screen, and controls three programmable output ports at the same time, which can greatly save and expand port resources. It is often used in digital products with LED screen display such as Bluetooth audio.
